The Synthesis and Characterization of Polyaniline Nanorod: by the Method of Ethanol Solution Polymerization

Polyaniline polymers were prepared using ethanol as solution in this paper while a kind of copolymer was formed with o-toluidine. And then the products were characterized and analyzed by the tests of infrared, electron microscopy and so on. The results shows that the products have the structure of nanorod, and the thermal stability of the copolymer proved to be worse than Polyaniline (PANI) after vulcanization process. Besides, the conductivity of the copolymer increased first and then decreased with the adding of o-toluidine, which is mainly due to the addition of polar groups methyl that affects π electron transfer speed on the molecular chain.
